Justification
A widespread, but poorly known species. It is suspected to be overlooked, and not in danger of extinction, but more field surveys are needed to confirm this.

Endemism
South African endemic
Provincial distribution
Eastern Cape
Range
King William's Town to Mount Frere.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Grassland, Savanna
Description
Sandstone grasslands, 600-1700 m.
Threats
Threats to this species are not known, but it is likely to be affected by habitat degradation due to overgrazing, which has led to a loss of plant species diversity as well as erosion across large parts of its range.
Population

This species is widespread across the eastern parts of the Eastern Cape, but has been seldom recorded. Its range falls within a botanically very poorly explored region, and it is possibly overlooked. Recent field observations indicate that it persists in the Indwe and Wodehouse districts. The population trend is not known, but it is possibly declining. More field surveys are needed to attain a better understanding of the population structure and trends.
